ZMF’s fluted, asymmetrical Caldera pad in all versions: perforated on top (TP), perforated on top and sides (TSP), fully perforated (Ultra Perf) and Wide Perforated Hybrid. One pair.
ZMF’s asymmetrical pad for Caldera, Atrium, Bokeh, Ori and Tessidera – in 15 versions
The Caldera Pad is ZMF’s own patent-pending pad: fluted on the inside, asymmetrical and slightly taller behind and below the ear for a good seal. Inside is a slightly firmer, gel-infused memory foam, outside leather or vegan suede. ZMF fits it as standard on the Caldera, Atrium, Ori, Tessidera and Bokeh, and thanks to its stretchy outer sleeve it also fits most large round headphones.

The sound is shaped mainly by the perforation. TP (Top Perf) is perforated on top only and combines the airflow of a perforated pad with the control of a solid one; ZMF recommends it for the closed models. TSP (Top & Side Perf) is also perforated on the sides and is the classic pad of the Caldera Open. Ultra Perf is perforated on the inside, top and sides and, according to ZMF, sounds more spacious and more linear; it is intended for the open models. The Wide Perforated Hybrid is its warmer counterpart: denser foam and more widely spaced holes for a fuller bass and a darker, punchier sound.
For the covering, ZMF’s rule of thumb applies: lambskin sounds warmer, suede more neutral, and hybrid pads with leather on the outside and suede towards the ear sit in between. For the Bokeh, ZMF also recommends the adapter rings so that the round pad sits firmly on the oval cup.
ZMF makes the pads by hand in the USA. We order your version directly from ZMF, so delivery takes approx. 4 weeks.
